Once the decorated farming urn is full, it becomes a decorated farming urn (full) and can be teleported to Ernie for 1,400 Farming experience or 1750 experience with urn enhancer. You may only own 10 full urns in your inventory/bank at once, if you have 10 full urns a new one will not be started.

It is recommended to take these urns when farming Yew trees or higher, as they will fill immediately, granting more experience per tree.
